Bed Plate Sealing

DFC adds an additional bead of high quality silicone to the bed plate inside the OEM silicone seal giving an additional layer of protection from potential bed plate oil leaks on all 6.0 and 6.4 engines.

Valve Seats

The factory induction hardened seat material is machined out and hardened SBI valve seats are installed in every intake and exhaust seat pocket preventing premature cracking in the future.


Our Rottler equipment allows us to remanufacture the Powerstroke engine’s to tighter than OEM specifications resulting in a longer lasting more efficient engine assembly.


DFC install new valves from Mahle/Clevite or SBI in every cylinder head we remanufacture. Most companies will re-grind and install used again.

Weighed Rotating Assemblies

Our production engines are typically matched with near identical weight piston and connecting rod assemblies giving our customers a smoother running and quieter engine.


ARP Head Studs

Our 6.0 engines come standard with ARP series 2000 head studs or OptiTorque head studs depending on availability to further enhance the engines durability by preventing head gasket failure.

Core Criteria

Ensuring every engine is built to the same high quality standards as the next DFC is very strict on what is remanufactured rejecting components that require considerable “restoring” to specifications.

Valve Springs

Instead of just testing old springs and reusing like most remanufacturers DFC install brand new SBI valve springs that are still tested for proper spring pressure on every cylinder head we rebuild.

Cast Guides

Common industry practice is to check guide clearance and if within specification, not replace. DFC considers this practice unacceptable and installs new cast SBI guides in every cylinder head we remanufacture.
